Der Arm-Cortex-M4-Prozessor wird von ARM mit der Eigenschaft efficient digital signal control belegt. Vergleicht man einen Arm-Cortex-M4-Prozessor mit einem Arm-Cortex-M3-Prozessor, dann geht es im Wesentlichen um die nachfolgenden Erweiterungen: DSP – Digital Signal Processor; FPU – Floating Point Unit; Die Gleitkommaeinheit ist optional.

The STM32F4xx series is based on a Cortex-M4 core. This includes a floating-point unit (FPU) which offers hardware support for single-precision IEEE-754 floats. It can improve your application's performance if you are performing floating-point operations. STM32F4 series of high-performance MCUs with DSP and FPU instructions The ARM ® Cortex ®-M4-based STM32F4 MCU series leverages ST’s NVM technology and ART Accelerator™ to reach the industry’s highest benchmark scores for Cortex-M-based microcontrollers with up to 225 DMIPS/608 CoreMark executing from Flash memory at up to 180 MHz operating frequency. Conceptually the Cortex-M4 is a Cortex-M3 plus DSP instructions, and optional floating-point unit (FPU). A core with an FPU is known as Cortex-M4F. Key features of the Cortex-M4 core are: ARMv7E-M architecture; 3-stage pipeline with branch speculation.

They also include the newest generation Bluetooth 5 Low Energy radio with high throughput (2Mbps) and Maxim's best-in-class hardware security suite trust protection unit (TPU). The answer is that the ARM Cortex-M4F has only a *single precision* (float) FPU, and not a double precision (double) FPU. As such it only can do float operations in hardware but not for double type.

Cortex-M4 and Cortex-M4F can do these operations more efficiently and fast compared to Cortex-M3. However, if you are using Cortex-M4 for applications which do not need DSP or FPU than using cortex-M4 instead of Cortex-M3 will give you no better results as the architecture of both of them are same.

In C the ‘f’ suffix can be used to mark constants as float: Basically I want to emulate a Arm-Cortex-M4F in qemu. I checked the docus, they say they support 2 boards from TI with M3 cores. They say they have support for Cortex M4. They say the FPU is active for ARM controllers.
